GigaWatt Circuit Breaker G-16A 2P

GigaWatt G-16A 2P is a 2-POLE circuit breaker intended to provide protection to  circuits within low-voltage electrical equipment 110-230VAC. It is used as an element of additional overload protection of GigaWatt LC-Y EVO cable power lines and GigaWatt power conditioners or power strips only. The G-16A 2P breaker is tested to DIN EN 60934 (VDE 0642):2013-11; EN 60934:2001+A1:2007+A2:2013 (circuits-breakers for household and similar applications) and must be used together with a main short-circuit protective device (SCPD) in front of it.2P_site

The 2P version has two working contact pins, and protects (cuts off) both the phase conductor and the neutral.

New type of breaker have a much greater resistance to the value of the instantaneous starting current (Hi-Inrush) than discontinued G-C20A 2P circuit breaker. This is extremely important due to the fact that audio-video devices (especially power-consuming power amplifiers) have different load characteristics from ordinary household power receivers. When the amplifier is turned on within the first milliseconds, the current consumed by such a receiver (starting current) can be up to 25 times higher than the current consumption during normal operation. The high inrush current causes the contacts in fuses and circuit breakers to burn, and consequently damage them.

This device is manufactured in the USA by Carling Technologies, according to GigaWatt specifications. It plays the role of an element controlling the value of current flowing through the power line in audio-video installations. The hydraulic-magnetic switch contains, among others, an induction coil that generates a magnetic field proportional to the current flowing through it. After exceeding a certain current value, the magnetic field causes the switch to operate precisely at the right time by opening the contacts and disconnecting the protected circuit from the current.

The advanced construction of the switch contains an innovative coil system, which has a core moving in a non-magnetic tube filled with special, oily fluid. This fluid can have different density, what allows for precise regulation of the delay characteristic and controlling the switching-off process. The switch is designed to ignore swift, peak load changes, which would trigger standard protection, and activates only when safe values are exceeded. This allows switching on inrush currents up to twenty five times higher than the nominal current (400A), which guarantees many years of failure-free operation.

The G-16A 2P installation switch does not have the typical shortcomings of thermal or case fuses, which are the result of their simple construction. All fuses – even the audiophile ones – besides the obvious protection capabilities, have one main weak point, which excludes them from usage in audio gear – they throttle the full power applied to the circuit. This flaw is the consequence of the very small diameter of the protective element, usually a thin copper, or silver wire – things the GigaWatt switch does not have.

The overcurrent switch G-16A 2P excels with a very solid construction, high quality of internal elements, resistance to vibration and working stability independent of the ambient temperature. The casing of the switch is made from black phenol-formaldehyde resin, what guarantees high rigidity. It is also fire proof, melt proof, antistatic, has a low electric and heat conductivity with relatively high mechanical resistance. Internal components, which take part in current conduction, are made from copper details and connectors with large cross-section, the coil itself is made from thick, copper wire, which does not cause any throttling or losses. The main contact elements are made from silver with a large contact surface.

The switch should be mounted on a standard DIN rail, and it can be connected to bare wire or spade connectors. The construction of the switch prevents the contact of the palm or fingers with live connection elements.
